exposes in a vertical position the underside of the packet with its slotopening for the extraction of the interleaved contents.

Whilst in this vertical position, a suction chamber carried on an arm isarranged to swing into position to partially withdraw the first leaf inThis suction chamber is provided with either one or two nozzle openingsas again from the pocket after plunging.a tendency which exists due tothe shallow depth of the side of the machine towards the centre, in thecase of the singles packing, and from both sides of the machine in theease of the doubles packing. In thedoubles packing it will be understoodthat the booklets lay side by side in the packet. ing it is necessary touse only one booklet feed The second feed required forthe doublespacking is arranged to be bolted on the opposite side of the bed and iscoupledto the first feed, and takes its drivefromthe same The feed,'whena singles booklet is required, can be adjusted immediately over thecentre line of the conveyor pockets The feeding forward of the bookletstowards the centre of the machine can be'byxany known means such as abelt conveyor andthe booklets are delivered to a platform arranged onthe centre line of the machine and situated just above the conveyorpockets. The booklets areremoved from the platform by means of a pusherwhich reciprocates in the direction of the conveyor pocket and deliversthe booklet (or booklets) in the case of the doubles feed, into theplunged cover which has previously passed beneath the platform and is inposition to receive same.

This pusher which is driven forward positively by a cam andspring-returned on to its cam, is arranged to be prevented fromreturning by means of a pin which is brought into its path in the eventof the nextsucceeding conveyor pocket containing no prepared cover.

A detecting finger is arranged to'be spring pressed through an aperturein the guide bar on to the cover, if present. If the cover is absent,the increased movement of the finger due to the absence of the coverbrings the aforesaid pin into the path of the pusher mechanismandprevents the pusher from returning; so missing one cycle of the feedingoperation of the pusher, and ensuring that the empty pocket does notreceive a booklet. The next cycle of operations releases the pin and,provided a cover is present in the next pocket, the pusher resumes itstravel and the supply of booklets.

After the subsequent folding and gumming operations which form no partof the present invention the pocket arrives opposite a pusher arrangedon the side of "the machine bed and operating transversely to the mainpocket conveyor. This pusher ejects the filled, tucked and partly foldedpacket into a receiver which is arranged vertically and to rotateintermittently, through an angle of 90, by means, preferably, of aGeneva drive wheel or the like.

The first stage in the rotation of this receiver In the case of thesingles pa'ckrequired according to whether a singles or a doubles packetis being operated upon.

The subsequent rotation movement of the re- .ceiver'is used to partiallyfold over the still upstanding flap of the packet and during the dwellperiod the packet is ejected horizontally out of the receiver away fromthe machine and delivered on to a plate or platform where the packetreceives a final pressing through a cam mechanism. During this ejectionthe final folding over of the flap is accomplished.

The packet remains on this platform until the ejection of a subsequentpacket which pushes the preceding one into a stacker where it iscollat'ed on edge for collection.

This invention is hereinafter more fully described with reference to theaccompanying draw- Figure 1 is a longitudinal side elevation partly insection of a machine constructed in accordance with this inventioncertain parts being omitted for the sake of clarity.

Referring to these figures it may be seen that the machine hereconsidered comprises an endless chain l arranged longitudinally of themachine frame and running over sprocket wheels 2 and 3. Rotary motionimparted to a drive wheel 4 on a shaft 5 at one end of the machine istransferred through gear wheels 6 and 1 to a further shaft 8 extendingalong the length of the machine and bearing at intervals drive wheelsand earns for operating the various component parts of the machine. Atits remote end the shaft 8 is operatively connected through bevel wheels9, lil and spur wheels ll, I2 to a crank l3. This crank is associatedwith a slide bar H! which slides in a slot in a boss 15 loose upon theshaft of the wheel 3. The wheel 3 is formed with a laterally projectingrim l6 which is slotted at regular intervals and a feather H on the sideof the slide bar M is arranged in the course of the rotation of thecrank E3 to engage in one of the slots in the rim I5 and turn the wheel3 by an amount equal to the interval between the spaced slotsr Operatingalternately with the slide bar M is a locking lever i8, I9 arrangedto beactuated by a cam attached to the wheel l2, the lever l9 hearing at itsend a detent 29 which by engagement in the slotted rim It looks thewheel Bin the intervals between the turning movements iinducedzbywtheslide bar I.

The booklet thereforeis left-fiat upon the platform 38 until the next advancing movement ofthe pusher when it is engaged by the extremity of said pusher andprojected into of the platform 38.

As the pockets on the chain approach the point where the booklets areinserted the main cover flap of each package projects to one side andpasses beneath a guide plate 45 where a detector device is furnished toensure that each pocket is properly furnished with a formed packagebefore booklet is delivered to the said pocket. This detector comprisesa feeler or finger iscarried by a. lever A! and arranged-to be movedtowards and from an aperture in the guide plate 45 by means of a spring48 and a rotary cam 49 respectively. Prior to arriving at the bookletfilling station each platform 2| stops adjacent this detector and ifapressed package is present the. eeler on rising will encounter the mainflap and re train the lever from following fully the denr ion in the cam49, and so permit but little mevement of a stop rod 50 which isconnected to'the lever 4'1." Alternatively if the flap isaha; "sent theextent of movement of the lever '41 will be determined solelyby the formof the cam and Twi l therefore enable the stop rode!) to interrupttemporarily the operation of the booklet delivthefeeler the stop rod 50will be projectedinto-" the slot 52 in the bar 5| and thus arrest-thereturn motion of the pusher causingthe booklet delivery mechanism tobeinactive during the next 'r-ycleof operation. During the next cyclehowever the stop pin 50 is released from the slot 52 in the bar 5! bythe action of the cams 49 and a! and rovided a formed package is presentin the next pocket, the pusher will resume its operatio and the deliveryof booklets;

After being filled with booklets the packagesare arrested at variousother stations'where operati ns such as the insertion of a stiffeningcard if desired. the folding and gumming of the flaps and the closing'ofthe package are successively Derformed but since these features form noessential part of the present invention the mechanisms concerned are notillustrated or described in detail.

However after the completion of these folding and cumming operations thepackets pass beyondthe ends of the guide plates 23'to a positiononposite a pusher '55 arranged on one side of the machine and arrangedto operate in ejecting the made up packets laterally from the pockets onthe conveyor chain. In line with this pusher but disposed on theopposite side of the machine is a receiver device see Figure 7comprising a rotary member 56 having four equally spaced hold- 61's 51adapted to accommodate the made up packets, these'holders successivelycoming into the formed package awaiting adjacent the endfirst leaf orsheet.

line with the pusher '55 as the member is sub jected toan intermittentrotary motion, a quarter revolution at a time. It should be understoodthat at this stage of the operation the packets are filled and closedbut the cover flaps remain in an open or extended condition and the slotthrough which the cigarettepapers are to be eX- tracted lies on theunderside of the packet. After being transferred from the conveyor chainto the rotary member thesucceecling rotation through a quartertu-rn ofthe rotary member brings the packetto a vertical position where theslotted front of the packet may be seen and inspected by the operator'in' charge. Moreover while the packet is-retained in this position asuction nozzle 10 carried upon an oscillating arm ll enters the slot inthe front of the packet and on receding again extracts the free edge fthe Following this action the rotary member 56 turns another quarterrevolution bringing the said packet once more to a horizontal positionbut this time inverted, and during this turning the cover'flap is partlyfolded about the packet by engagement-With a curved plate 58. Havingarrived at this point the packet is ejected from the holder in therotary member 555 by suitable means and delivered to a plate 59 wherethe folding down' of the cover flap is completed and the package issubjected to a final pressing by an oscillating presser plate 60.

The packet remains on this platform until the ejection. of a subsequentpacket causes it to be pushed into'amagazine 6| where the completedxpackets are collated on edge ready for removal from the machine as Iclaim:
